what is the Stefan-Boltzmann constant ??
In: 1
Every object emits light due to its heat. Hotter objects emit more light. The Stefan-Boltzmann law describes how much is emitted:
*M = σT^4*
Where:
* M is the radiant exitance, the amount of energy emitted per unit surface area per unit time
* σ = 5.67×10^−8 W m^−2 K^−4 is the Stefan-Boltzmann constant
* T is the temperature of the object
If an object is a ‘black body’, then it *only* emits light due to its heat; this could be that it’s so bright that reflected light is negligible (e.g., the Sun).
